an aqueous solution of a new antimalarial drug was prepared by dissolving 42g in 1L of solution at 24 °C. the density of the solution is 1.0375 and the antimalarial drug has a molecular weight of 181.29. Calculate the molarity, molality, mole fraction of the components and percent by weight of antimalarial drug

In this reaction n2o4(g)→2no2(g) what changes in color would you expect as pressure is increased at a constant temperature
